| In recent decades, numerous studies have sought to better understand the mechanisms underlying the compatibility between Biomphalaria glabrata and Schistosoma mansoni. The developments of comparative transcriptomics, comparative genomics, interactomics and more targeted approaches have enabled researchers to identify a series of candidate genes. However, no molecular comparative work has yet been performed on multiple populations displaying different levels of compatibility. Here, we seek to fill this gap in the literature. We focused on B. glabrata FREPs and S. mansoni SmPoMucs, which were previously demonstrated to be involved in snail/schistosome compatibility. We studied the expression and polymorphisms of these factors in combinations of snail and... |

| Background The cattle gastrointestinal tract (GIT) is the main enterohemorrhagic Escherichia coli (EHEC) reservoir. In order to identify nutrients required for the survival or multiplication of EHEC in the bovine GIT, we compared the transcriptomes of the EHEC O157:H7 reference strain EDL933 cultured in vitro in bovine digestive contents (DCs) (rumen, small intestine and rectum) using RNA-sequencing. Results Gene expression profiles showed that EHEC EDL933 activated common but also specific metabolic pathways to survive in the different bovine DCs. Mucus-derived carbohydrates seem important in EHEC nutrition in posterior DCs (small intestine and rectum) but not in rumen content. Additional carbohydrates (xylose, ribose, mannitol, galactitol) as well as... |

| Tracheliastes polycolpus is an ectoparasitic copepod that recently emerged in western Europe and that infects several freshwater fish species. Its recent successful spread might be due to its fascinating ability to shift to new host populations and/or species. Here, we present the first non-redundant and protein-coding de novo transcriptome assembly for T. polycolpus along with a quality assessment and reliable transcript annotations. This assembly was built from fifteen adult female parasites sampled from three different host species from a single river in southwestern France. Overall, 17,157 non-redundant contigs likely corresponding to protein-coding transcripts were identified, of which 13,093 (i.e., 76%) were successfully annotated. This assembly... |
